    My first problem with my Mac since I got it. It crashed black screen of death I think they call it. Will boot I see apple logo then scrolling gray screen and says you must restart you computer. Safe mode won't change anything, resetting NVRAM and or PRAM, Unplugging power cord to reset SMC didn't work. The hard drive was put in another Mac and shows data, repair person did a disk repair and extracted crucial files I needed. So my question is could all the memory failed at once? Because Iv'e swamped out some memory and replaced different sets 4x2GB not Apple memory but been in machine for over a year with no problems.

    Have you run specific RAM tests to check the RAM, or can you not even get that far? Rember used to be a decent tool to test, but there may be better options out there for testing now.

    Any power surges recently? I've never actually had ALL memory go at the same time. Only a few bad sticks over the years, so I guess I've been lucky in that respect. If all the memory is showing as failing, then I would think it's probably motherboard issue, or an issue with the memory card board.

    You mean it always doe this - like every time or something? Or just once?

    Will it boot from the CD or thumb drive?

    We need more information. And we need better (clear and precise) sentence structure please.
